Found a good one! Carl Pyrdum's blog, titled Got Medieval, is a treat for us geeks who enjoy the old timey stuff; specifically, medieval stuff. Pyrdum is a grad student in Medieval Studies at Yale. His posts typically have to do with things medieval and/or modern things which either describe themselves as, or could be seen as medieval. Where else are you going to read about what a sixty-fourmo is in the blogorama?
So how did I find him: it was this entry on 'Why are books so big? (Google Penance)' which describes why books are the size that they are. Its based on the size of a sheep of course. I won't spoil the fun for you, you should just clicky-click on the link and read it fer yerself. Of course the whole thing makes complete sense once you read it, and I found myself scanning through lots of his blog posts in search of more gems and witicisms.
Carl also points out that he is Bacon number 4. You can find out how at his blog.
